I believe every lutz he tried got a call, and without looking at his program, and ignoring the steps/turns prior to the jumps, I would have said his LP had no flutzes and several flips. It's a pretty solid flutz.
We know that at this Event Samarin was a substitute for last moment, he arose only at "Online results".
Why?
At August this year he had surgery of appendicitis, and for last moment doctors did not make final decision, may he compete or not.
Decision was made a day before flight to competition - at last possible moment. Not because before this moment were real problems, but to have a varranty that his health will not suffer.
Ordinary skaters in Russia have physical examination once a season (before the season, to have right for training and competitions). Members of Team Russia - four times the year, each three months. More intense skating - more often testing of health.
